Implantable medical device system having implantable cardioverter-defibrillator (ICD) system and substernal leadless pacing device
First Claim
1. A method of providing electrical stimulation therapy to a heart of a patient using an implantable cardioverter-defibrillator (ICD) system and an implantable leadless pacing device, the method comprising:
- generating one or more pacing pulses with the implantable leadless pacing device;
delivering the one or more pacing pulses via two electrodes on a housing of the leadless pacing device implanted substantially within an anterior mediastinum of the patient such that the two electrodes on the housing are physically isolated from a pericardium of the patient;
generating a defibrillation pulse with an ICD of the ICD system implanted within a patient; and
delivering the defibrillation pulse via at least one electrode of a defibrillation lead coupled to the ICD.

Abstract
Implantable cardiac systems and methods for providing substernal pacing in an ICD system are described. In one example, an implantable cardiac system comprises an ICD system and an implantable leadless pacing device (LPD) communicatively coupled to the ICD system. The ICD system includes an ICD and an implantable defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation shock to a heart of the patient. The LPD includes a housing, a first electrode on the housing, a second electrode on the housing, and a pulse generator within the housing and electrically coupled to the first electrode and the second electrode. The housing of the LPD is implanted substantially within an anterior mediastinum of the patient and the pulse generator is configured to deliver pacing pulses to a heart via the first and second electrodes.
